IN VEN TCR FGHNK J @ARIE/50N #l5 A TTOE NE Y United States Patent O3,098,493 PEE FR SMKING TBACCO Frank J. Garrison, 1031 Riverview Ave.,Dayton, Ohio Filed (Bat. 16, 1961, Ser. No. 145,201 2 claims. (ci. isi-203) This invention relates to an improved pipe for smoking tobacco.

It is among the objects of the present invention to provide a pipe forsmoking tobacco with means for accumulating and trapping the foultasting moisture usually found in a pipe after repeated use. This meanssubstantially prevents the moisture from being drawn through the bitinto the mouth of the user.

A further object of the present invention is to provide a pipe withmoisture accumulating and trapping means, which is remote from the bitof the pipe and over or through which the smoke does not pass as it isdrawn from the bowl of the pipe, through the bit and into the mouth ofthe user.

Further objects and advantages of the present invention will be apparentfrom the following description, reference being had to the accompanyingdrawings showing preferred forms of construction embodying the featuresof the present invention.

In the drawings:

FIG. l illustrates a pipe having a one-piece stem and bit to which thebowl portion of the pipe is removably attached, this bowl portioncooperating with the stem to form a moisture accumulating and trappingchamber.

FIG. 2 shows a pipe similar to the one shown in FIG. l, the stem,however, being removably attached to the bit and forming an intermediatechamber in said stem.

FIG. 3 shows a pipe having a one-piece stem and bowl, the bit beingremovably attached to the stem and forms an intermediate chamber in thestem. This chamber is remote from but directly connected with themoisture accumulating and trapping chamber in the stem and independentof the bowl portion thereof.

FIG. 4 is a detail, elevational view of the removable bowl portion ofthe pipe.

1n smoking tobacco in a pipe, a Very undesirable condition presentsitself, that is, the accumulation of a foul tasting moisture in thesmoke conducting passages of the pipe, caused by condensation and theadded drivel by the user of the pipe.

Attempts have been made to mitigate this condition by providing moistureaccumulators or absorbers directly inside the smoke conducting passageof the pipe. Such arrangements are effective for a very short period ofuse for, as the deterring elements in the smoke passage become chargedwith the ill tasting moisture, the smoke laden air being drawn throughand over the said moisture charged elements will become contaminated andtake up the foul taste of the moisture. Eventually the moisture itselfmay be drawn into the mouth of the smoker with the ill tasting, smokeladen air.

This inefficient arrangement and its undesirable eiiects are practicallyavoided in the pipe of the present invention. Here the moistureacoumlating chamber and its contained absorbing element is remote fromthe pipe passage through which the smoke laden air is drawn andconducted to the mouth of the user. Said chamber and its containedelement is connected with the smoke conducting pipe passage at a pointremote from said chamber, thereby eliminating direct contact of thesmoke laden air with the accumulated, foul tasting moisture in the saidchamber and its contained element. This feature permits the moisture,particularly the smokers drivel to flow directly into the accumulatingchamber, remote from the smoke passage of the pipe. Suction on the pipestem for smoking purposes will have no substantial with- Mice drawingetect upon the moisture in the accumulating chamber.

Referring to the drawings, particularly FIG. l, the pipe has a main bodyportion y20, and integral therewith the stem portion 22, and bit portion23. These three portions may be made of any suitable material capable ofbeing molded, such as plastics or the like. A bowl 21, preferably madeof wood, and hollowed out to form the tobacco combustion chamber 26, hasan exteriorly threaded extension 27, which is received by the interiorlythreaded recess in the body 20 of the pipe, for removably attaching thebowl to 21 to said pipe body. The inner surface of bowl extension 27forms the ceiling of the moisture accumulating chamber 24 in saidrecess. An annular groove 28 is provided in its extension 27, saidgroove being in communication with the interior 26 of the bowl 21through passage 129. A passage 25 opens into the moisture receivingchamber 24 and extends throughout the entire length of the integral stemand bit portions 22 and 23 respectively. A smoke conducting conduit 26has its one end opening into the passage 25 at a point remote from themoisture chamber 24, and extends upwardly through the body portion 20 ofthe pipe and communicates with the interior of the bowl through groove28 and passage 29'.

To assist in the retention of the fluid moisture accumulated in thechamber 24, a wad or pad of absorbent material 3i) is replaceable heldtherein by the bowl 21. This substantially prevents the back ilow ofliquid moisture from chamber 24 into the bit 23.

When this pipe is used, air drawn through the burning tobacco in bowl 21will become smoke laden and pass through opening passage 29 into thecommunicating, downwardly inclined passage 26, connecting passage orduct 25, and enter into the users mouth. Inasmuch as this flow of smokeladen air is remote from, and in no way passes over or through the foultasting moisture accumulated in chamber 24, the smoke laden air, drawninto the mouth of the fuser, will not be contaminated. Inclination ofthe smoke passage 26, upwardly from its point of connection with theduct 25, will substantially prevent the drivel of the smoker to flowinto the bowl area of the pipe, but on the contrary, said drivel willflow through duct -25 into the moisture accumulating chamber 24.

The pipe shown in FIG. 2, is substantially like the one shown in FIG. 1,excepting that the bit portion 123 is removably attached to the stemportion 122. Here the end of the stem portion '122 has a recess 131,which receives the reduced end 132 of the bit portion l123. The recess131 in the stem is longer than the reduced portion 132 of the bit 123,thus forming the intermediate chamber 133 within the stem 122. Duct '134in the stem directly connects the intermediate chamber with the moistureaccumulating chamber 124. Duct 125 in the bit 123 opens into theintermediate chamber `133. The inclined smoke conduit 126 opens into theintermediate chamber 133 and communicates with the interior of the bowl121 through passage 129 in said bowl. An absorbing pad 130 is providedin the chamber 124. It will be noted that the intermediate chamber isremote from the accumulating chamber and that the smoke conduit opensinto the upper area of said intermediate chamber 133.

The pipe shown in FIG. 3, differs from those of FIGS. l and 2 in thatthe bowl portion 221 is not removable, but is integral with the stemportion 222. Like the pipe of FIG. 2, it has a detachable bit portion223, provided with a reduced diameter end 232 which is insertable intorecess 231 in the end of the stem portion 222, and forms an intermediatechamber 233 therein. In the bottom of the stem portion, contiguous tobut not in direct communication with the bowl portion 221, there isprovided an interiorly threaded recess having a removable sealing plug240 which forms the moisture accumulating chamber 2214 within saidrecess. A moisture absorbing wad or pad 230 in said chamber isreplaceable by removal of said plug 240. A smokewconduit 2216 provides adownwardly inclined communication between the interior of the bowlportion 221 and the intermediate chamber at its upper area. Duct 234 inthe stem portion 222 directly connects the intermediate chamber 213-3with the moisture accumulating chamber 224. The duct 225 in stem portion223 opens directly into the intermediate chamber 233.

The features of the present invention are readily adaptable to beembodied in a pipe having a curved stem and bit. These featuressubstantially isolate the flow of the smoke laden air from the area ofmoisture accumulation andrconsequently said air will not be contaminatedand ruined by the foul tasting, accumulated moisture.

In the proposed constructions the pipe may easily be cleaned and theabsorbent wad or pad may readily be removed and replaced Awith a wad ofcotton, sponge or other material having moisture absorbing qualities.
